Short-Time Decoherence and Deviation from Pure Quantum States

, 2004
In systems considered for quantum computing, i.e., for control of quantum dynamics with the goal of processing information coherently, decoherence and deviation from pure quantum states, are the main obstacles to fault-tolerant error correction.

Loss-tolerant operations in parity-code linear optics quantum computing [PDF]

, 2007
A heavy focus for optical quantum computing is the introduction of error-correction, and the minimisation of resource requirements. We detail a complete encoding and manipulation scheme designed for linear optics quantum computing, incorporating scalable

Preserving a qubit during state-destroying operations on an adjacent qubit at a few micrometers distance

Nature Communications
Protecting qubits from accidental measurements is essential for controlled quantum operations, especially during state-destroying measurements or resets on adjacent qubits, in protocols like quantum error correction.
